A safety control device and a control method of motor vehicle license plate manufacturing equipment

Abstract

The invention provides a safety control device of motor vehicle license plate manufacturing equipment, which can prevent the problem of data leakage or tampering of a license plate in a recognition process, and can prevent a license plate manufacturing point from manufacturing the license plate by using non-recorded license plate manufacturing equipment, so that the whole license plate manufacturing process is in a controllable state. Meanwhile, the invention further discloses a safety control method based on the safety control device. The safety control device comprises a national cryptographic algorithm safety chip, and the national cryptographic algorithm safety chip is in USB communication with a license plate making device main control CP and an identification shooting unit through aUSB-HUB chip; Data communication with the license plate manufacturing equipment electromechanical control device is carried out through an RS232 serial port, the working voltage of the license plate manufacturing equipment electromechanical control device is monitored through a switching value detection module, and an electronic valve of the license plate manufacturing equipment electromechanicalcontrol device is controlled through an electronic valve driving switch module.

Description

technical field [0001] The invention relates to the technical field of motor vehicle number plate production, in particular to a safety control device and control method for motor vehicle number plate production equipment. Background technique [0002] The existing motor vehicle number plate production equipment includes equipment control PC, number plate production equipment electromechanical control device, number plate production application software running on the equipment control PC; the general production process of motor vehicle number plate production is: the operator logs in and runs The number plate production application software on the control PC of the number plate production equipment requests production from the number plate management information system through the public security network or private network; the number plate management information system responds to the request, generates the number plate queue information to be produced, and transmits it to ...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the problems in the prior art that it is impossible to prevent the use of non-record number plate production equipment at the production site, and to prevent the number plate data from being leaked or tampered with during the identification process, the present invention provides a safety control device for motor vehicle number plate production equipment. It can prevent the problem of data leakage or tampering during the identification process of the number plate, and can make the number plate production site unable to use non-recorded number plate production equipment for number plate production, so that the entire number plate production process is in a controllable state
